FOR most 75-year-olds, walking 296km in 12 days is probably the last thing they'd want to do.
But, for Tamworth Citizen of the Year Mike Cashman, it's in his DNA.
That's probably why he's currently trekking from the New England town to Newcastle as part of Casho's 'Holy Grail' Walk for the Men of League Foundation.
Along the journey, which includes stop-overs at Wingen, Aberdeen, Muswellbrook and Singleton this week, the retired teacher is raising funds - and awareness - for the valued organisation.
"I've always been a fitness fanatic," Mr Cashman said while in the Upper Hunter on Monday.
"Over the years, I have completed six marathons, 22 half-marathons, 36 City to Surf races and much more.
"Even to prepare for my Holy Grail, I racked up 5100km over 30-odd weeks during training.
"I built up to 120-165km weekly.
"The only worry I have is the 46km stretch from Muswellbrook to Singleton [on Tuesday].
"That's nine hours of continuous walking - it's the big test.
"However, I'm fit and confident.
"I've had a good response to my 'excursion' so far.
"A couple of people even offered me a lift but I declined," he added with a laugh.
Mr Cashman decided to tackle the challenge as a way to celebrate his 75th birthday, while linking his hometown of Newcastle to his adopted home of Tamworth.
He aims to walk into McDonald Jones Stadium, just in time for the Knights' final round NRL encounter with the Gold Coast Titans on August 31.
That showdown coincides with the club's Old Boys Day.
"Even though I've been involved with the [Tamworth] Men of League for the past six years, I'm a rugby league fan," he said.
"And, it must be said, a Knights' tragic.
"Although I don't really want to talk about the weekend's result.
"I was born in Newcastle - and have barracked for them since they started in 1988.
"They've supported my Holy Grail, too.
"The Knights provided a package to auction, at Port Stephens, which raised $1400.
"West Tamworth Leagues Club also chipped in with $1000.
"I've picked up a further $670 on the road as well.
"All the money will go towards those in the league community who are in need.
"I know what the foundation does.
"It's great at looking after a lot of local families."
